Google had made it clear that page loading time is a key factor in ranking web pages. Organic traffic is dependent on SERP positions. So the higher you rank, the better will be your blog traffic.

There are different ways to optimize wordpress website speed for better ranking to getting conversions, sales and sign-ups. The average page load times depend on various factors like number of JS, CSS, HTMl resources included in it.

How Page Loading Time is Tested

The best way to measure how fast a page loads can be done using the Page Speed metric. This can be interpreted in “page load time” (the time taken to fully display content on a page” or “time to first byte” (time taken to receive the first byte information from the server).

Tools used to test Page Loading Time

Google’s PageSpeed Insights tool can be used to measure this parameter. It will test any web page for mobile and desktop version. If you get a high score or green color, it indicates that your page is loading blazing fast.

GTMetrix and Pingdom Tools are other two services which run your website through different servers and spit out the time taken to load a page.

Each tool has its own way of reporting its results. For example, GTMetrix gives page loading time when tested from Canada server. Pingdom Tools has more options to test from USA, Europe etc.

What does Google say on PageSpeed

Google has outwardly spoken that site speed is a ranking signal. Research has shown that time to first byte is a key factor in measuring page speed. If you have a slow site, search engines can crawl only few pages. This will have a bad affect on your indexation.

If a page takes more than 3 seconds to load, visitor is more likely to leave the site.

The number of requests also drastically came down when using PageSpeed Ninja plugin.

Compared to SG Optimizer plugin, the test results in all the 3 tools show better score and less page loading time, when using PageSpeed Ninja plugin.

Also to use SG Optimizer plugin, you need to have use SiteGround hosting for your WordPress sites. Since these two sites are almost bone structure pages with little JS, CSS, HTML code, the efficiency of PageSpeed Ninja plugin could not be fully tested.

Which is the best WordPress Cache plugin of PageSpeed Ninja and SG Optimizer?

More plugins and JS code will show a better conclusive result.

One definite conclusion is that page loading time has decreased to below 2 seconds for all the 4 pages tested using PageSpeed Ninja plugin for both AMP and Desktop pages.
